- the invention aims in particular to provide the body with a said set of bodywork elements whose arrangement is suitable for allowing its installation on a vehicle whose architecture has an aesthetic line along which the rear face of the vehicle is significantly inclined in relation to the rolling plane of the vehicle.
- a problem posed is that such an aesthetic line of the vehicle spares a small space for installing the anchor member of the reel on the body.
- said space for implanting the reel anchoring member on the body is contained between a reinforcement ring and a rear wheel arch formed by a quarter lining. It should also be taken into account that said space is likely to be congested by at least one body reinforcement extending between the reinforcement ring and the quarter panel lining, in particular to provide resistance of the body to torsion in the event of vehicle shocks.
- the reinforcing ring is formed of one or more components by providing all or part of a roof belt longitudinally and transversely to the vehicle and / or a belt of a rear opening of the body providing rear access to the vehicle interior.

- Another object of the invention is to provide such an anchoring via a set of bodywork elements which can be generally contained in a limited space. Without limitation, it is particularly intended to be able to accommodate said set of bodywork elements between a reinforcing ring and a quarter panel lining providing a rear wheel arch, under the constraint of an orientation of the rear face of the body which is significantly inclined relative to the rolling plane of the body.
- Another object of the invention is to provide the anchoring of the reel on the body via a said set of bodywork elements having a desired minimum mass and / or comprising a limited number of components.
- Another object of the invention is to reduce the vehicle costs associated with obtaining and / or installing on the vehicle said set of bodywork elements.
- the aims of the present invention are achieved individually or in combination by applying the following provisions.
- a motor vehicle body comprises at least one set of bodywork elements configured as an anchoring member on the body of a reel of a seat belt.
- the set of bodywork elements comprises a support for receiving the reel fixed to at least one deformable bodywork element which is itself fixed to the body and which is configured to deform at a predetermined force threshold, especially in the event of an impact (s) suffered by the vehicle.
- a set of bodywork elements covered by the invention is capable of forming a said anchoring member on the body of a reel of a seat belt equipping either a rear seat or a seat front if there is no rear seat on the vehicle.
- the invention is recognizable in that the support is on the one hand fixed to an anchoring structure on the body of a vehicle seat backrest and on the other hand to at least one component of a body reinforcement.
- the body reinforcement is interposed between a reinforcement ring bordering a rear opening of the body and a quarter liner providing a rear wheel arch.
- Such a body reinforcement is in particular configured to strengthen the body in torsion.
- Said body reinforcement is constitutive of said deformable body element comprising at least one weakening zone allowing its deformation to said force threshold essentially according to a tensile force oriented along the longitudinal extension of the body.
- the body reinforcement is in particular configured as a body for reinforcing the body in torsion in the event of impacts to the vehicle, by being fixed to the reinforcement ring and to the quarter panel lining, in particular by welding.
- the body reinforcement is arranged as a body reinforcement member which is typically capable of deforming overall in torsion when it is subjected to torsional forces in the event of shocks to the vehicle and therefore to the body.
- Said tensile force is exerted in particular on the body reinforcement via the support, being oriented along the longitudinal extension of the body as a result of a possible displacement of the anchoring structure of the seat back towards the front of the body in the event of an impact to the vehicle and therefore to the body.
- the body reinforcement is able to deform via said at least one weakening zone which it comprises according to a predefined configuration of tensile deformation in the longitudinal direction of the vehicle.
- Such a deformation in traction of the body reinforcement makes it possible to limit the transmission of said tensile force to the welds of the body reinforcement fixing it to the body, in order to preserve their integrity and therefore the quality of the fixing of the body reinforcement to the ring. reinforcement and on the wheel arch.
- the welds thus preserved make it possible to maintain the ability of the body reinforcement to deform in torsion, while providing absorption of the tensile force generated as a result of a displacement of the structure d anchoring of the seat back.
- said welds of the body reinforcement are provided via lugs fitted to the body reinforcement which extends substantially vertically and transversely between the reinforcement ring and the wheel arch. Said welds are in particular distributed over the body reinforcement for its application respectively on the reinforcement ring and on the wheel arch in substantially transverse and vertical directions of extension of the body. It is understood by the introduction of the concept substantially that said transverse, vertical and / or longitudinal orientations of extension of the body reinforcement and / or of the support are not considered strictly but essentially or in other words in an approximate manner depending on the configuration of the location area of the bodywork assembly on the body.
- the support is fixed by bolting to the body reinforcement, via a first bolt passing jointly through a wing extending the support and a reinforcement element at least partially constituting the body reinforcement.
- the body reinforcement may include one or more components formed of reinforcement elements assembled together.
- the body reinforcement can be formed from a single-piece body or from being made up of several components which each consist of a reinforcement element and which are assembled together, in particular by abutment in the vertical direction of separation between the reinforcement ring and the quarter lining.
- a first reinforcing element of the body reinforcement can be formed by the wing extending the support and via which the latter is fixed to a second reinforcing element of the body reinforcement to which it is abutted.
- a first weakening zone of the body reinforcement comprises a passage of the first bolt through it. At least said passage is deformable via the first bolt to said force threshold under the effect of a traction exerted by the support on the body reinforcement as a result of a displacement of the anchoring structure.
- Such a passage is in particular formed by an orifice formed through the component of the body reinforcement to which the support is fixed.
- the bolt can be integrated into the wing, in particular by welding.
- the wing also includes an orifice for the passage of the first bolt through it, in order to avoid making its structure more complex and to simplify the organization of the methods of deformation of the body reinforcement in torsion.
- play is made between the first bolt and said passage.
- Such a clearance makes it possible to increase the faculty of deformation of said passage through the first bolt to said force threshold reached by the traction force, as a function of the effective orientation of the application of the traction force on the reinforcement. checkout.
- stiffening ribs are formed on the wing at the edge of a passage which it comprises for its crossing by the first bolt. Such ribs also make it possible to contain the deformation of the body reinforcement by the first bolt, which makes it possible to avoid excessive weakening of the body reinforcement liable to affect its torsional strength in the event of shocks to the body.
- stiffening ribs are formed on the wing on either side of a passage through the first bolt. Such ribs are in particular formed on the face of the wing which is opposite to its face for fixing to the component of the body reinforcement.
- a second weakening zone of the body reinforcement is formed by at least one window formed through it and allowing a flexural deformation of the body reinforcement at said stress threshold in the direction of the traction force. applied to it via the support.
- the window is formed on the body reinforcement below the area for fixing the support on the body reinforcement, and is bordered by a belt constraining the deformation of the body reinforcement by the tensile force. to said flexural deformation.
- said anchoring structure is fixed to the body at least by bolting via a second bolt which provides a tilting axis of the anchoring structure on the body allowing its movement in the event of an impact to the vehicle .
- the tilting of the anchoring structure is notably caused in the event of impacts to the body, with the effect of generating said tensile force on the support which is then transmitted to the body reinforcement via the first bolt, with the effect of causing its deformation.
- the second bolt is preferably placed in the lower zone of the anchoring structure to amplify the tensile force generated from a threshold of movement of the low amplitude backrest.
- the support is inclined relative to the rolling plane of the body and relative to the body reinforcement.
- the support is inclined towards the upper part of the box from the front towards the rear of the box at a first angle of inclination.
- the body reinforcement is inclined towards the upper part of the body from the front towards the rear of the body according to a second angle of inclination formed between the support and the body reinforcement and considered from the support towards the ring of reinforcement.
- the first angle of inclination of the support relative to the rolling plane of the body is between 10 ° and 40 °.
- the second angle of inclination between the support and the body reinforcement is between 100 ° and 130 °.
- Such angle values are in particular to be adapted according to the architecture of the body and in particular according to the space available between the reinforcing ring and the quarter liner.
- the support may or may not be part of the body reinforcement.
- the body reinforcement is formed of a one-piece body, the ends of which are respectively fixed on the reinforcement ring and on the quarter panel lining. Said component of the body reinforcement on which the support is fixed via the wing which extends it, is then formed of said one-piece body.
- the body reinforcement comprises at least one upper reinforcement element and a lower reinforcement element which are fixed to one another via one of their ends.
- a second end of the upper reinforcement element is fixed to the reinforcement ring and a second end of the lower reinforcement element is fixed to the quarter panel lining.
- the upper reinforcement element and the lower reinforcement element are separate from the wing extending the support.
- the support is then indifferently fixed via the wing to the upper reinforcement element and / or to the lower reinforcement element.
- the support can advantageously be part of the body reinforcement. More particularly according to this other embodiment, an extension of the support is part of the body reinforcement, of which it forms a first component fixed on the one hand to the reinforcement ring and on the other hand abutting a second component of the reinforcement of body itself attached to the quarter liner. Said extension of the support is in particular formed of the wing which is integral with the support and which is used to form the first component of the body reinforcement.
- the body reinforcement comprises the wing forming a first of its components fixed to the reinforcement ring and fixed abutting, in particular via the first bolt, to a second component of the body reinforcement formed by a reinforcing element which is itself fixed to the quarter panel lining.
- the number of parts making up the reel anchoring member on the body is thus limited to two, while promoting the transmission of the tensile force from the support to the body reinforcement and promoting resistance to torsion of the body reinforcement notwithstanding the presence of the window which is then formed through the second component of the body reinforcement.
- Figures 1 and 2 are perspective representations of a motor vehicle body, illustrating for example the general context of the invention.
- Figures 3 to 5 are details of the body shown in Figures 1 and 2, illustrating an embodiment of a set of bodywork elements of the invention and mounted on the body.
- a body 1 of a motor vehicle extends longitudinally L1 from front AV1 to rear AR1, transversely T1 between its right and left sides and vertically V1 in elevation from its rolling plane P1.
- the rear face 2 of the body 1 generally extends along a plane P2 significantly inclined relative to the rolling plane P1 of the body 1, in order to give the vehicle a line specific aesthetics typically appreciated as being sporty.
- the body 1 provides a frame giving the vehicle its robustness, especially in the event of violent shocks to the vehicle as a result of an accident.
- the body 1 comprises in particular a reinforcing ring 3 which forms a belt bordering a rear access to the passenger compartment of the vehicle.
- Such an access is conventionally formed by an opening 4 made in the rear face 2 of the body 1 and designed to receive a rear window.
- the reinforcing ring 3 is formed as an extension of a reinforcing belt of the body 1 bordering at least partially the roof of the vehicle.
- the reinforcing ring 3 thus participates in the resistance of the body 1, in particular in torsion, to protect the passengers of the vehicle in the event of severe shocks.
- the body 1 is also used for anchoring various equipment to the vehicle, including in particular seats (not shown).
- the architecture of the body 1 is designed to receive front passengers, including the driver of the vehicle, and rear passengers. In particular with regard to the rear passengers, these are intended to be installed in a rear seat commonly arranged in the bench.
- the rear seat is fitted with passenger seat belts, which are anchored to body 1 on its right side and on its left side.
- Such seat belts are commonly equipped with a retractor fitted with a tension sensor to cause them to lock in the event of an impact to the vehicle.
- the retractors are conventionally anchored to the body 1 in areas located behind the rear seat on the right and left sides of the vehicle respectively. The problem therefore arises of the anchoring of the reel on the body 1, in particular under the constraints of the inclination of the rear face 2 of the body 1 and of the methods provided to protect the passengers in the event of impacts sustained by the vehicle.
- the reel is capable of being installed at the rear:
- -) either from a rear seat, such as in particular arranged in a seat, in the case where the body 1 is configured to receive front passengers and rear passengers, -) or from a front seat in the case where the body 1 is configured to receive only front passengers.
- the inclination of the rear face 2 of the body 1 limits the space E1 that may be available at the rear of the seat between the reinforcement ring 3 and a rear wheel arch 5 formed by a quarter panel lining 6.
- a body reinforcement 7 contributing to the resistance of the body 1, in particular in torsion, is commonly installed in said space E1 in interposition between the ring reinforcement 3 and the wheel arch 5.
- the invention proposes to equip the body 1 with a set of bodywork elements configured as an anchoring member on the body 1 with a reel (not shown) with a seatbelt.
- the anchoring member comprises in particular the body reinforcement 7 and a support 8 for receiving the reel.
- the support 8 is of flat conformation P3 by being formed of a plate on which the reel is intended to be fixed.
- the support 8 extends along its plane P3 between the body reinforcement 7 and an anchoring structure 10 of the seat back intended to be equipped with the seat belt.
- the support 8 is fixed on the one hand to the body reinforcement 7 via a first bolt 11 and on the other hand to the anchoring structure 10 via a third bolt 12.
- the anchoring structure 10 is provided with at least a keeper 13 via which the seat back is fixed to the anchoring structure 10.
- the anchoring structure 10 is mounted on the body 1 via at least one second bolt 14 oriented in the transverse direction T1 of the body 1.
- the body reinforcement 7 comprises two components, one of which is formed of a reinforcing element 15 arranged in platinum and the other of which is formed of a wing 16 extending the support 8 along the plane P4 of extension of the reinforcement 7.
- the wing 16 and the reinforcing element 15 are fixed to each other via the first bolt 1 1 abutting one another according to the extension of the body reinforcement 7 between the reinforcement ring 3 and the quarter panel lining 6.
- the wing 16 on the one hand participates in the body reinforcement 7 by forming one of its components, and on the other hand forms an assembly member via the first bolt 11 between the support 8 and the other component of the body reinforcement 7 consisting of the reinforcement element 15.
- the body reinforcement 7 is fixed by welding to the reinforcement ring 3 via the wing 16 and is fixed to the quarter panel lining 6 via the reinforcement element 15.
- the wing 16 has first legs fixing 17a, 17b which bear against the reinforcing ring 3 respectively and essentially vertically V1 and transversely T1.
- the reinforcing element 15 comprises second fixing lugs 18a, 18b which bear against the wheel arch 5 respectively and essentially vertically V1 and transversely T1.
- the body reinforcement 7 comprises weakening zones 19a, 19b to allow its deformation in the event of impacts sustained by the vehicle as a result of a displacement of the seat back.
- the displacement of the backrest can in particular result from its pivoting around the second bolt 14 causing the backrest to tilt forward AV1 of the body 1. It is particularly intended in this case to avoid a break in the tension sensor fitted to the reel, to limit the movement of the backrest via the belt while avoiding injuring the passengers, and / or above all to avoid a break in the welding of the body reinforcement 7 on body 1.
- the backrest exerts on the support 8 a tensile force C1 in the longitudinal direction L1 of the body 1. Therefore, such a tensile force C1 is transmitted to the body reinforcement 7 by the support 8 via the first bolt 1 1 forming a tie essentially oriented longitudinally L1.
- the support 8 exerts in particular said tensile force C1 on the body reinforcement 7, via the first bolt 11 which is essentially oriented longitudinally L1.
- the weakening zones 19a, 19b of the body reinforcement 7 then allow its deformation when the tensile force C1 exerted by the support 8 on the body reinforcement 7 is greater than or equal to a predefined force threshold.
- a first weakening zone 19a of the body reinforcement 7 is formed by a passage through which the first bolt 11 which is formed through the reinforcement element 15 in its upper part via which the support 8 is fixed to the element of reinforcement 15.
- a clearance is preferably made between the first bolt 11 and said passage that comprises the reinforcement element 15.
- the first bolt 11 causes a deformation of the passage of the reinforcement element 15 which it crosses. More particularly according to the example illustrated, the first bolt 1 1 then causes at least one deformation of the upper part of the reinforcing element 15, in particular by tearing the reinforcing element 15 around the passage which it comprises and / or by deformation of this passage. The deformation of the upper part of the reinforcing element 15 provides a first absorption of the tensile force C1.
- Ribs 20 are preferably formed on the wing 16 at the edge of a passage which it comprises for its crossing by the first bolt 1 1, to reinforce its resistance against its excessive deformation as a result of the force of traction exerted by the support 8 on the reinforcing element 15.
- the ribs 20 also make it possible to contain the deformation of the reinforcing element 15 in its first weakening zone 19a, in order to avoid excessive weakening of the body reinforcement 7 in torsion.
- a second weakening zone 19b of the body reinforcement 7 is formed by a window 21 formed through the body reinforcement 7.
- the window 21 is formed through the reinforcement element 15 below its zone of attachment with the support 8 and has a belt 22 at its periphery.
- the body reinforcement 7, and more particularly the reinforcement element 15 and the wing 16, extend along a plane P4 essentially vertical / transverse V1 / T1 which is oriented perpendicular to the orientation of the tensile force C1 exerted by the support 8 on the reinforcing element 15.
- the support 8 provides a seat for the reel by extending essentially along a longitudinal / vertical plane P3 L1A / 1 to transmit the tensile force C1 to the element reinforcement 15.
- the tensile force C1 transmitted to the reinforcement element 15 via the support 8 causes it to bend in the second weakening zone 19b along the plane P4 of the reinforcement element 15.
- a such a deflection of the reinforcing element 15 limits a weakening of the body reinforcement 7 vis-à-vis its torsional strength due to the presence of the belt 22 bordering the window 21.
- the essentially vertical extension V1 of the bodywork reinforcement 7 and the essentially horizontal extension of the plane P3 of the support 8 are appreciated as general orientations, apart from their moderate inclination relative to the rolling plane P1 of the body 1.
- the longitudinal extension L1 of the support 8 is conditioned by the size of the reel and the available separation distance between the anchoring structure 10 and the body reinforcement 7.
- the vertical extension V1 of the body reinforcement 7 is conditioned by the separation distance between the reinforcement ring 3 and the wheel arch 5. Given the limited space E1 available for installing the body reinforcement 7 and the support 8 on the body 1, these are preferably moderately inclined relative to the rolling plane P1 of the body 1 to allow an increase in their extension along their respective planes P4, P3.
- the support 8 and the body reinforcement 7 are inclined relative to the rolling plane of the body 1 in the direction of the reinforcement ring 3 from the front AV1 towards the rear AR1 of the body 1.
- the support 8 is inclined relative to the rolling plane of the body 1 and the body reinforcement 7 is inclined relative to the support 8.
- the inclination of the support 8 relative to the rolling plane of the body 1 is substantially equivalent to the relative inclination between the body reinforcement 7 and the support 8.
- the angle of relative inclination between the support 8 and the body reinforcement 7 is between 100 ° and 130 °
- the angle of inclination of the support 8 relative to the rolling plane P1 of the body 1 is between 10 ° and 40 °.
- Such angle values provide an acceptable compromise between, on the one hand, optimization of the extensions of the body reinforcement 7 and of the support 8 along their respective planes P4, P3 and, on the other hand, their orientations relative to each other and with respect to the plane. rolling of the body 1. It is understood that said angle values are in particular to be adjusted according to the architecture of the body 1, in order to obtain a satisfactory transmission of the traction force C1 from the support 8 towards the component 15 of the body reinforcement 7 to which the support 8 is fixed.
